Solution of the present invention does not comprise biological buffer commonly used.So-called " conventional buffers " means and a kind ofly makes pH remain on the chemical compound of a particular range in the solution that exsomatizes.So-called " biological buffer commonly used " means a kind of chemical compound that makes pH remain on scope biology of 7~8 in cell-free system.The example of biological buffer commonly used comprises N-2-hydroxyethyl piperazine-N '-2-hydroxy-propanesulfonic acid (HEPES), 3-(N-morpholino) propane sulfonic acid (MOPS), 2-([2-hydroxyl-1,1-two (methylol) ethyl] amino) ethyl sulfonic acid (TES), 3-[N-trihydroxymethylaminomethane base]-the 2-hydroxyethyl]-1-piperazine propane sulfonic acid (EPPS), three (methylol) aminomethane (THAM) and trihydroxymethylaminomethane methylmethane (TRIS).Biological buffer commonly used is independent of normal biological processes and plays a role, for example, conventional buffers in live body not by metabolism, and the strongest in cell-free system.
Solution of the present invention uses normal biotic component to keep living body biological pH, i.e. a notion that is called " dynamic buffering system ".This dynamic buffering system notion is based on present inventor's following discovery: in live body can by metabolism, in biological scope the chemical compound of no intrinsic buffer capacity, interact as lactate, with other solution composition and keep biologically suitable pH in animal body, even in hypothermia and basically also can be like this under the depletion of blood situation.Dynamic buffering system of the present invention partly depends on Oxygenation and carbon dioxide (CO 2) remove; And allow but additional bicarbonate (NaHCO not necessarily will be arranged 3).Dynamic buffering agent of the present invention does not have or does not have basically ability to serve as buffer agent beyond the biosystem, and promptly a kind of dynamic buffering agent can be in the living body biological scope but can not be kept pH in acellular environment.A kind of composition of dynamic buffering agent of the present invention comprises a kind of carboxylic acid, its salt or ester.So-called carboxylic acid, its salt or ester mean the chemical compound that its general structural formula is RCOOX, R is alkyl, alkenyl or aryl in the formula, side chain or straight chain, contain 1~30 carbon, on these carbon substituent group can be arranged, and better be one of the carbochain that constitutes the carbochain of lactate, acetate, citrate, pyruvate or other biological metabolite; X be hydrogen or sodium or other can on the oxygen position, connect biologically can compatible ion substituent, or contain the short straight or branched alkyl of 1~4 carbon, as-CH 3,-CH 2CH 3
As shown in table 1, a kind of initial pH of typical commonly used buffer solution (25mM TRIS) is about 7.7, keeps the pH more than 7.2 when adding 0.12ml 1.25M HCl solution nearly.Otherwise the pH of HLB solution (initial pH7.7) drops to below 7.2 when the about 0.01ml 1.25M HCl solution of interpolation.
When using solution of the present invention, add the aseptic NaHCO of pharmaceutical grade in the thermotropism sterile solution (HL solution) as the low temperature blood substitute 3This NaHCO that contains 3Solution be called HLB solution.HLB solution sees Table 1 in the buffer capacity for biological buffer commonly used in the cell-free system.Having under the condition of living body of Oxygenation, in the temperature of 1.6~36.1 ℃ of these scopes, HLB solution obviously can make pH remain on (table 2 and 3) more than 7.3.
When solution of the present invention when normal body temperature is used as plasma extender, need not to add NaHCO 3Just can make live body pH remain on scope biology.
Use not existing of biological buffer in the solution of the present invention always, invested and made this solution heat-killed important medical advantage regularly.In general, medical solution better is regularly to carry out heat sterilization before being used for the patient." regularly heat sterilization " used herein or " heat sterilization " this term mean and relate under pressure in 15 minutes the process that a kind of solution is heated to 120 ℃, that is: make heat and one section time enough of pressure condition maintenance, to kill all or all antibacterials and make all in the solution or all are virally inactivated basically basically.This step is normally carried out in autoclave, thereby is also referred to as " autoclaving ".Heat-killed purpose is to kill the infectious agent that may exist in the solution.The known temperature that tolerates up to 100 ℃ of infectious agent.Technical it is generally acknowledged under pressure, makes a kind of solution be heated to 120 ℃ and keeps just being enough to guarantee aseptic in about 15 minutes.
All grafts or blood substitute solution that the present inventor knows all can not tolerate regular heat sterilization.Be known that the solution more than the pH7.0 is carried out a large amount of degradeds that heat sterilization can cause other solution composition.
Otherwise solution of the present invention is designed to be and can carries out heat sterilization, and the degraded of other solution composition such as sugar is insignificant.HL solution carries out heat sterilization before use.When NaHCO is added in hope 3During with formation HLB solution, NaHCO 3Be to add in the aseptic HL solution as a kind of commercial aseptic 1M solution that gets.In general, every liter of HL solution adds 5ml 1MNaHCO 3Solution forms 1L HLB solution.Yet, can add more NaHCO 3
HLB solution of the present invention or its buffering organic acid and salt also can be used for supporting in vitro tissue and the cell cultivated.The dynamic buffering system of this solution can make the tissue of cultivation and cell remain on suitable biological pH.We are verified, and adding lactate and bicarbonate in cultured cells is enough to support normal cell growth and form.
Solution of the present invention comprises a kind of organic carboxyl acid or its salt." organic carboxyl acid or its salt " this term comprises can be by metabolic any carboxylic acid of mammal or carboxylic acid derivates.The carboxylic acid and the carboxylate example that are suitable for solution of the present invention comprise lactate and sodium lactate, citrate and sodium citrate, gluconate and gluconic acid sodium salt, pyruvate and Sodium Pyruvate, succinate and sodium succinate, and acetate and sodium acetate.In the example that following explanation HLB solution uses, adopt sodium lactate.When carrying out the live body metabolism, lactate helps to keep the bicarbonate level, thereby plays a kind of effect that can keep the composition of living body biological pH in the solution dynamic buffering system of the present invention.
In order to further describe the present invention, will discuss as a kind of aqueous solution according to mixture of the present invention.From the following description of the present invention, be expected to make personnel that the mixture of dry mixture form can be provided with the general technical ability of this gate technique, and can carry out necessary adjustment to the quantity of sodium chloride and organic sodium salt, can be used as the sodium chloride quantity of finding in the normal-salt aqueous solution that the diluent according to dry mixture of the present invention uses to hold.
The quantity of organic sodium salt is calculated in such a way: consider the Na ion concentration that exists in the experimental subject blood, and to the sodium chloride concentration of any solution that wherein adds dry ingredients.The quantity of adding will make that obtaining Na ion concentration from this organic sodium salt is enough to make Na ion concentration this solution to reach the Na ion concentration of normal blood plasma on the physiology.Therefore, when the quantity of considering the sodium ion that obtains from organic sodium salt and sodium chloride or concentration, the Na ion concentration in this solution approximately is exactly the Na ion concentration of finding in the normal blood plasma on the physiology.
This solution also comprises certain density calcium, sodium and magnesium ion, and they are in described in the blood plasma within the ionic normal physiological concentration range.In general, the desirable concentration of these ions obtains from dissolved calcium, sodium, magnesium chloride salt, and under the situation of sodium, is to obtain from the also organic sodium salt of the dissolving solution.
Na ion concentration better is in the scope of 70mM~about 160mN, is more preferably in the scope of about 130~150mM.
Calcium ion concentration is more preferably in the scope of about 2.0mM~2.5mM in the scope of about 0.5mM~4.0mM.
Magnesium ion concentration is more preferably in the scope of about 0.2mM~0.45mM in the scope of 0~10mM.The high concentration magnesium ion importantly, in according to solution of the present invention, do not comprise excessive magnesium ion, because can produce harmful effect to the active intensity of heart contraction.In better embodiment of the present invention, this solution contains the Mg of inferior physiological amount ++
Chlorine ion concentration in the scope of 70mM~160mM, 110~125mM Cl more fortunately -Scope in.
This solution also comprises a certain amount of simple hexose such as glucose, fructose and galactose, wherein is preferably glucose.In better embodiment of the present invention, use be hexose, and can use sugar mixture.In general, the concentration of sugar is in the scope of 2mM~10mM, and the concentration of glucose better is 5mM.Often it is desirable to improve the concentration of hexose, in the hope of reducing the body fluid hold-up in the experimental subject tissue.Therefore, the expanded range of hexose can be arrived up to about 50mM, to prevent or to limit the experimental subject generation edema that is subject to processing if necessary.
The swelling agent is by such molecular composition: its size is enough to prevent that them from entering between idiosoma organization the matter space and circulate and lose because of passing the capillary bed window.As one group, the example of swelling agent is a plasma extender.
The human serum albumin is a kind of plasma protein that is used for increasing the blood plasma volume.Also known have a polysaccharide, generally is characterized by the dextran polymer that can be used as plasma extender.In general, be preferably, polysaccharide is nonantigenic.
(McGaw is a kind of from almost completely formed, introduced the deutero-artificial colloid of waxy starches of hydroxyethyl ether group the glucose unit that α (1-4) connects by amylopectin Inc.) to Hetastarch.The colloidal nature of 6% (weight) Hetastarch solution approaches human serum albumin's colloidal nature.Other polysaccharide derivates also can be suitable as according to the swelling agent in the solution of the present invention, comprising methylol α (1-4) or (1-6) polymer.Cyclodextrin is the swelling agent that is suitable for.
Can use the D-glucose polymer.For example, glucosan, promptly α (1-6) key is connected to main D-glucose, and the swelling agent that can be used as in the solution of the present invention is used.Better be that molecular weight ranges is 30,000~50,000 dalton's (D) polysaccharide such as glucosan.Best is molecular weight is about 40, the Gentran 40 of 000D.
High molecular weight polysaccharide, for example molecular weight is about 70, and the macrodex of 000D is generally not too desirable, because they have increased the viscosity of colloid solution, thereby has damaged high flowing velocity.Yet for some purposes, why more desirable high-molecular-weight dextran solution is, just is that they can more effectively prevent to organize swelling, because they are lower from speed that capillary tube spills.Therefore, such high-molecular-weight dextran solution is particularly useful for treating cerebral ischaemia under hyperbaric oxygen tension force, also can be used for effectively controlling cerebral edema.Under these circumstances, may it is desirable to use the higher molecular weight polysaccharide, for example molecular weight ranges 50,000~70, the glucosan of 000D.
When in according to solution of the present invention, using Gentran 40, use about 8% (weight) Gentran 40, or about 80 grams (80g/l) of every premium on currency.Molar concentration scope according to blood substitute of the present invention is about 290~330mM, is preferably molar concentration and is about 300mM.Best is that final molar concentration is about 298mM.
This polysaccharide concentration (adding the chloride salt of sodium, calcium, magnesium, the organic ion of organic sodium salt and hexose discussed above) is enough to reach the colloid osmotic pressure that approaches normal human's serum, promptly about 28mmHg.
This solution can cooperate with oxygen or hyperbaric oxygen under normal body temperature, perhaps has or do not have hyperbaric oxygen, is used for perioperative experimental subject as a kind of circulation solution.This solution also can descend to such an extent that significantly be lower than the intra-operative of the normal temperature of experimental subject at the body temperature of experimental subject, is used for experimental subject as a kind of circulation solution.During the homoiothermic animal experimental subject is exposed to surgical operation and low temperature corpse organ supply process in cryogenic conditions the time, in general it is desirable to the blood of experimental subject is changed into cold circulation solution of the present invention, or with solution of the present invention circulation a period of time, be intended to perfusion and keep this experimental subject and organ constant in the intra-operative former state.
Solution of the present invention can be applied to through intravenous or through intra-arterial and is placed on oxygen concentration and increases to up to the euthermic experimental subject under the pressurization atmosphere of 100% oxygen, or be applied to a kind of like this experimental subject that is undergoing surgery, the body temperature of this object of intra-operative descends to such an extent that significantly be lower than the normal temperature of this object, and no matter whether uses hyperbaric oxygen.When solution of the present invention is applied to this experimental subject and by this experimental subject circulation time, various medicaments such as heart fiber crops agent both can also can add in the circulation solution of the present invention to the direct administration of the blood circulation of this experimental subject, to the directly administration of cardiac muscle of this experimental subject.Add these compositions and be in order to reach desirable physiological effect, for example to keep heart contraction activity clocklike, stop the cardiac fibers vibration, or suppress the contraction movement of cardiac muscle fully.
